About Jit

Whale has a built-in Jit Engine, When you have more advanced Hook requirements, you can directly generate executable instructions in memory through the Jit.
There is no longer the need to generate ugly hard code through tools as before.

Compile

We have pre-built binary versions of Android & IOS. You can find them in the built directory.

Whale uses CMake to build projects, so you need to install CMake on your system.

Android

If you need to use Java Hook please copy java folder to your project.

Direct use of binary，You just copy the files under built/Android to src/main/jniLibs in your project.

If you need to compile the source code, specify CMakeLists.txt in build.gradle:
